HENRY M. HOLIGREWE, OF ST. LOUIS, MISSOURI.

KNOCKDOWN DRA'WER.

Application filed July 6, 1912.

To all whom it may concern:

Be it known that I, HENRY M. HOLTGREWE, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Knockdown Drawers, of which the following is a specification. I

This invention relates to improvements in knock-down drawers for cupboards, sideboards, dressers, chiifonniers and other like furniture wherein drawers are applicable and has for its object hinged sides connected to the head piece or front of the drawer and so arranged as to be permitted to fold parallel with the same so as to permit the entire members constituting the drawer to be folded up to occupy a small amount of space, found desirable for shipping purposes.

A further object of my invention is to construct a drawer so arranged as to be folded together, the sides arranged to fold against the front parallel therewith and when unfolded and arranged into a complete drawer and the parts connected together will form a perfect and rigid structure.

Figure 1 is a perspective view of my complete invention in its assembled position. Fig. 2 is a horizontal sectional view. Fig. 3 is a vertical sectional view. Fig. 4c is a perspective view showing the front piece and the two sides folded one against the other. Fig. 5 is a detail perspective view ofthe tail piece. Fig. 6 is a perspective view showing all of the parts constituting the drawer in folded position and packed together. Fig. 7 is a detail perspective View of a corner of the drawer showing the hinges by which the sides and ends are connected together countersunk.

Referring to the drawings in detail 8 indicates the front end or head piece of a drawer, 9 and 10 the side pieces, 11 the tail piece and 12 the bottom. The front end or head piece 8 is provided with the usual flange 13 projecting from the body portion so as to hide from view the construction of the drawer or the ends of the side pieces; the body portion is provided at each end with a recess 14 forming a mortise, the remaining projecting portion 15 acting as a tenon; the side pieces 9 and 10 are also provided with recesses 16 which correspond in size and permit the insertion of the projection 15 so that when the side pieces and Specification of Letters Patent.

front end or head piece are arranged together as shown in Fig. 2 a rigid and unique oint is formed. Upon the upper and lower edges of the side pieces 9 and 10 are located hinges 17 constructed in the form of bellcrank levers, the arms 18 of the hinges connected to the upper and lower edge of the side pieces by means of pins 19, and the arms 20 of the hinges are pivotally connected to the upper and lower edge of the front or head piece by means of the pins 21; by this construction the ends 9 and 10 are permitted to be folded against the front end or head piece and arranged parallel therewith as shown in Figs. 4. and 6, and by means of the pivotal construction of the hinges and of their bell-crank nature the said sides will spread sufficiently so as to accommodate the insertion of one side between the other side and the front piece. The opposite ends of the sides 9 and 10 are provided with dovetailed grooves 22 which are arranged to accommodate the insertion of the dovetailed ends 23 of the tail piece 11, the said sides are also provided with horizontal elongated grooves at extending throughout their length, the body of the front end or head piece 8 being likewise provided with a corresponding groove 25; in these grooves is permitted to be seated the edges 26 of the bottom 12.

The essential feature of my invention is the construction of a drawer having its side members hingedly connected to the front end, the contacting edges being suitably tongued and grooved or otherwise mortised and tenoned to provide a rigid structure when assembled in its intended position yet by the folding feature or knockdown principle each drawer is folded very compact and the entire number of drawers shipped with a piece of furniture which is also of the knock down nature will take up but very little space in proportion to the amount of space occupied by the entire number of drawers when shipped in their ordinary position.

In Fig. 7 I show the same principle of hinge, the same in this event being countersunk or located in a recess 27 so that its .upper surface is on a level with the edges of the sides and front end of the drawer which is necessary when this structure is used in connection with high class furniture. This structure of drawer has been more particularly designed to be used on drawers of kitchen cupboards and cabinets which are constructed on a knock-down principle and bottoms would be packed one on top of the other, the remainder portion of the drawer folded and laid on top of the bottom side by side in a position similar to that shown in Fig. 6; when so packed the two drawers would occupy about one-fourth less space than that occupied by one of the drawers when in its extended position.

Having fully described my invention what I claim is:

1. A drawer of the class described comprising a front piece, a pair of side pieces, a tail piece and a bottom, the same being suit ably grooved to permit each member to be connected to the other and L-shaped strips acting as hinges connecting the top and bottom edges of the front piece to the top and bottom edges of the side pieces for permitting Copies of this patent may be obtained for the said side pieces to be folded against the front piece and over each other, substantially 2. A drawer of the class described comprising a head piece, the ends being suitably tongued and grooved, a single pair of side pieces being correspondingly tongued and grooved and arranged to interlock with the ends of the front Piece and Lshaped strips acting as hinges connecting the top and bottom edges of the side pieces with the top and bottom edges of the front piece so as to permit said side pieces to fold over each other and against the front piece for arranging the drawer in a compact knock-down and folded position'for shipping purposes, and recesses formed in the edges to allow the hinges to be countersunk forming a flush joint, substantially as specified,

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

HENRY M. HOLTGREWE.
